IMPROVEMENT lN MACHINES FOR PUNCTURlNG PAPE R.

Specification forming part of Letters Patent No. I 78,937, dated JuneApril 22, 1876.

To all whom it may concern:

Be it known that I, ALEXANDER N. LEWIS, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Puncturing Machines, which improvement is fully set forth inthefollowing specification, reference being had to the accompanyingdrawings.

The object of my invention is to puncture at one time any number ofthicknesses of paper or other material, and aftersuch puncturing towithdraw the puncturing knife or instrument from the material withoutdisturbing its position in the machine, so that the material canreadilybe removed therefrom. This is accomplished by means of anadjustable cylinder attached to the lower arm of the machine, andcapable of being regulated to the thickness of the quantity of paper ormaterial to be punctured, through which the puncturin g-rod passeswhenforoed downward by pressure on the knob, and which prevents thepaper or material from being displaced when the rod, on being releasedfrom pressure, is forced upward by means of the spiral spring, as shownin the drawing.

In Figure 1 of the accompanying drawing, A represents the frame, withthe base P and the arms B and O, through which the puncturing-rod Hpasses. The puncturing-rod H is kept from turning by means ofthe pin J,which passes through the arm B into a inortise or slot, M, in thepuncturing-rod. It is also prevented from traveling too far upward bymeans of the pin I, which passes entirely through it, projecting oneither side, so as not to pass through the aperture of the arm B.

L is a spiral spring, coiled around the rod H,-

between the pin 1'. and the arm 0, sothat when the puncturing-rod, afterhaving been forced downward by pressure on the knob K, is released frompressure, it will force the puncturing-rod upward by acting on the pin Iand 'the arm 0.

Fig. 2 is a vertical section of the machine.

20, 1875; applicationfiled D represents the adjustable cylinder, capableof being moved upward or downward over the shoulder E of the arm 0, andof being fastened into position by the binding-screw F. N represents thepuncturing knife or instrument, which is inserted into the ends of thepuncturing-rod H, and fastened there by a screw or otherwise. R is theaperture in the base of the machine, into which the puncturing-knifeenters after passing through the paper or material punctured. O is anadjustable gage, by which the distance of the puncture from the edge ofthe material can be regulated and made uniform.

In operation the material to be punctured is placed under the adjustablecylinder D up to the gage O; the adjustable cylinder D is then loweredto the surface of the material; the. knob K of the puncturing-rod H isthen pressed or struck, forcing the puncturing-rod H down through theadjustable cylinder D, and the puncturing knife or instrument N throughthe material. Immediately upon the knob K being relieved from thepressure, the puncturing-rod H is forced upward by the action of thespring L, and the puncturing knife or instrument N is disconnected fromand raised above thematerial, which is held down in position by means ofthe adjustable cylinder, and can be readily removed from the machine.

I claim as my invention-- 1. The combination, with a puncturing-rod, H,of the adjustable cylinder D, whereby varyin g thicknesses of materialmay be perforated, all substantially as shown and described.

2. In combination, the puncturing-rod H, supported substantially asshown, spring L, adjustable cylinder D, knife N, and slotted base P, allsubstantially as-and for the purpose set forth.
